designation: Bellows DN 15
Materials: Aluminium casting / PTFE virgin
Purpose of use: flexible connection of glass/pipe systems
Type: 2-flanged, sprung with clamping screws
Type: 2-flanged, sprung with clamping screws
The Bellows DN 15 Type PF out of Cast aluminum with a high-quality PTFE virgin-Inner liner is a compact, chemical-resistant component for glass assemblies or process lines with high requirements for flexibility, tightness and media resistance. Ideal for use in conjunction with glass reactors or vacuum/pressure systems.
The system consists of the parts shown in the pictures.
Condition: used, but unused and in original packaging, incl. protective caps and clamping screws.
Advantages:
- PTFE virgin – highest chemical purity & media resistance
- Flexible use for compensating thermal expansion or vibrations
- Compatible with PF flange systems in laboratory and engineering
- Safe sealing even with changing pressures or temperatures
- Robuste Bauweise durch Aluminium-Flanschplatten

2. General functions
- Provides connection of two rigid components (e.g., glass reactor and piping)
- Reduces vibrations, stresses, or temperature fluctuations
- Suitable for use in vacuum or light overpressure areas
- Suitable for aggressive media by PTFE virgin inner body
- Installation e.g. between reactor lid and pipe system or pump supply line

3. CO₂ savings
By purchasing this used but unused bellows, the energy-intensive production of a new part is avoided.
Estimated savings: 200–250 kg CO₂
(Reference: PTFE components with metal flanges, medium component size)
